摘要
基于Autodesk平台的BIM技术在水运工程结构设计中缺少一款与建模软件Revit匹配的结构计算软件,为此提出一种将通用有限元结构计算软件ANSYS与Revit耦合的方法。由于Revit仅在族环境中才能建成水运工程参数模型,所以先对Revit基础图元类型进行编程分类,把可载入族赋予结构属性。采用RevitAPI技术过滤结构模型的几何信息、属性信息、材质信息,再将提取信息编译成ANSYS命令流文件,实现结构计算软件ANSYS与BIM建模软件的数据转换,并依据Revit布尔算法优化ANSYS结构计算前处理的映射网格划分步骤。最后使用某船闸主体工程进行验证,证明本方法在结构计算中运用是可行性的。
The BIM technology based on Autodesk platform lacks a structural calculation software matching the modeling software Revit in the design of water transport engineering structure.A method for coupling general finite element structural calculation software ANSYS and Revit is proposed.Since Revit can only build the water transport engineering parameter model in the family environment,the Revit basic primitive types are programmed and classified to give structural properties to the loadable family.The Revit API technology is used to filter the geometric information,property information and material information of the structural model,and then the extracted information is compiled into ANSYS command stream file to realize the data transformation of structural calculation software ANSYS and BIM modeling software,and optimize the mapping grid partitioning process of ANSYS structure calculation based on Revit Boolean algorithm.Finally,the feasibility of this method in structural calculation is verified by using the main project of a ship lock.
